Ernesto Valverde said the world stops when something happens to Lionel Messi as the Barcelona head coach expressed his concern over the forward's latest injury.
The 32-year-old was taken off at half-time of Barca's 2-1 LaLiga victory over Villarreal on Tuesday due to an adductor injury.
It was the Barca captain's first start of the season after overcoming a calf injury, however Valverde said he didn't want to take any risks with Messi.
"When something happens to Messi the world stops, not only here," he told a news conference as Marca reported.
"I don't think it's serious. We don't want to take any risks. We will see tomorrow [Wednesday], I can't tell you anything now.
"He has been injured for a long time and we don't want to take any risks at the moment."
